CONNECTED RIDERS

I am very happy with my INNOV-K2 that has been on my bike since I bought it on 25th June 2019, I'm getting even more fun from it since I've mastered the basics of a video editing piece of software. My problem is that the speed regularly does not display, in fact it is rarer that it does display. This is frustrating as it's like one of those intermittent hard to find problems. I get a solid GPS light on the unit and the remote module has a nice clear view of the sky. So any ideas how I can fix this?

I bought a new iPhone SE, I was on a iPhone 7 and now the Innovv K2 app does not connect anymore, I do not have the old phone so the K2 is useless to me. I see on the Internet several issues with the app, very bad. I'm very disappointed with the Innovv K2. I do not recommend it at all.
